Assessment of vibration amplitude and transmembrane pressure on vibratory shear enhanced membrane filtration for treating dairy wastewater

Abstract In this study, statistical analysis was performed to investigate the influence of operational parameters based on experimental results. The research aimed know whether a long-term discontinuous module vibration operation is possible without adversely affecting filtration efficiency. Polymer membranes were compared by surface characteristics with contact angle measurements and selected for further membrane experiments dairy wastewater treatment. effect main parameters, amplitude ( A vibr . ) transmembrane pressure TMP ), investigated using vibratory shear enhanced processing VSEP ultrafiltration UF nanofiltration NF membranes. Components permeates, including chemical oxygen demand COD measured, rejections calculated compare threshold limit values. results suggest that proper combination could mitigate fouling. However, resulted in more clogged lower fluxes, but slightly higher rejections. We conclude investigating significance necessary wider, energy environment-friendly application
